Constructor Detail

PofSparseArray

public PofSparseArray(PofValue valueParent,
                      ReadBuffer bufValue,
                      PofContext ctx,
                      int of,
                      int nType,
                      int ofChildren)

Construct a PofSparseArray instance wrapping the supplied buffer.

Parameters:

valueParent - parent value within the POF stream

bufValue - buffer containing POF representation of this value

ctx - POF context to use when reading or writing properties

of - offset of this value from the beginning of POF stream

nType - POF type identifier for this value

ofChildren - offset of the first child element within this value

Method Detail

findChildInternal

protected PofValue findChildInternal(int nIndex,
                                     int ofStart,
                                     int iStart)

Find the child value with the specified index.

Specified by:

findChildInternal in class ComplexPofValue

Parameters:

nIndex - index of the child value to find

ofStart - offset within the parent buffer to start search from

iStart - index of the child value to start search from

Returns:

the child value

instantiateNilValue

protected PofSparseArray.NilPofValue instantiateNilValue(int of,
                                                         int nIndex)

Instantiate a PofSparseArray.NilPofValue (factory method).

Parameters:

of - offset this value would be at if it existed

nIndex - index of this value within the parent sparse array

Returns:

a NilPofValue instance
